## **Core Concept**
The lateral orbital wall is a critical structure in the anatomy of the orbit, providing protection and support to the orbital contents. It is formed by specific bony structures that fuse together during development. Understanding the composition of the orbital walls is essential for diagnosing and managing orbital trauma and surgical interventions.

## **Why the Correct Answer is Right**
The lateral orbital wall is primarily formed by the **frontal process of the zygomatic bone** and the **orbital surface of the greater wing of the sphenoid**. These two bones articulate to create the lateral boundary of the orbit. The zygomatic bone contributes significantly to the lateral wall and floor of the orbit, while the greater wing of the sphenoid forms part of the lateral wall and the posterior aspect of the orbit.

## **Why Each Wrong Option is Incorrect**
- **Option A:** Incorrect because it does not accurately represent the bones forming the lateral orbital wall.
- **Option B:** Incorrect as it may confuse the bones contributing to other orbital walls or the overall structure but not specifically the lateral wall.
- **Option C:** This option might list bones that contribute to other parts of the orbit or to the facial skeleton but are not primarily responsible for forming the lateral orbital wall.

## **Clinical Pearl / High-Yield Fact**
A key clinical correlation to remember is that fractures of the lateral orbital wall can lead to significant complications, including entrapment of extraocular muscles and potential vision loss. The zygomatic bone's contribution to the lateral wall and floor makes it a common site for fractures in orbital trauma.

## **Correct Answer:** D. Frontal process of zygomatic bone and orbital surface of greater wing of sphenoid.
